Abstract

To introduce productive and new forage plants, a 3-year research (1379-1381) was conducted to evaluate the effects of PLANT DENSITY on quantitative and qualitative characteristics of FORAGE SORGHUM in second cropping. The test was carried out as split plot in R.C.B.D (Randomized Complete Block Design) with 4 alterations in Khoy agricultural research Station. The density of 200, 250, 300, 350 thousand shrubs per hectare was considered as primary factor level and the kinds of Speed feed, Sugargraze and Jumbo as secondary factor levels. The result of analysis of compound data variances showed that an increase in shrub density on the surface unit leads to the reduction of plant paw and the thinned stalks. Also, a decrease in space between plants and their density-350,000 per hectare- affects in the increase of plant height, leaf surface indices and the proportionate increase of leaf to stalk. On the whole, maximum cropping yield was attained in dry and wet silage and protein in the surface unit with 350,000-plant density. Of the samples experimented, Speed feed yielded the maximum cropping of wet and dry silage of 75 and 14.5 tons per hectare respectively. Meanwhile these figures about the other qualities of Speed feed such as: plant height, number of leaves and paws, leaf surface indicator and protein yield were higher than of Jumbo and Sugargraze. Ultimately, plantation of Speed feed FORAGE SORGHUM with 350,000 PLANT DENSITY as the second cropping was recommended to Khoy Farmers.
